1 Maxim Integrated SPI-based USB 2.0 host controller MAX3421E
2
3 Required properties:
4 - compatible: Should be "maxim,max3421"
5 - spi-max-frequency: maximum frequency for this device must not exceed 26 MHz.
6 - reg: chip select number to which this device is connected.
7 - maxim,vbus-en-pin: <GPOUTx ACTIVE_LEVEL>
8 GPOUTx is the number (1-8) of the GPOUT pin of MAX3421E to drive Vbus.
9 ACTIVE_LEVEL is 0 or 1.
10 - interrupts: the interrupt line description for the interrupt controller.
11 The driver configures MAX3421E for active low level triggered interrupts,
12 configure your interrupt line accordingly.

14 Example:
15
16 usb@0 {
17 compatible = "maxim,max3421";
18 reg = <0>;
19 maxim,vbus-en-pin = <3 1>;
20 spi-max-frequency = <26000000>;
21 interrupt-parent = <&PIC>;
22 interrupts = <42>;
